Genus Chirosia
Most adults are distinguished from most Anthomyiidae by the development of strong medial rows of bristles on abdominal tergites 3-5 in addition to the usual apical rows. Hylemya has similar rows on tergites 4-5 only, and has a plumose arista unlike most Chirosia.
Widespread. The distribution of the genus generally follows the distribution of ferns, being absent from deserts.
Larvae develop in ferns.
